(Reuters) - A former Insys Therapeutics Inc district sales manager was arrested on Thursday on charges that he participated in a scheme to pay kickbacks to doctors to prescribe a drug containing the opioid fentanyl, U.S. prosecutors said.

Jeffrey Pearlman, 49, was charged in a criminal complaint filed in federal court in New Haven, Connecticut, becoming the latest individual to face prosecution in connection with probes involving Insys' drug Subsys.
